i have a 1997 528i and recently when i attempt to engage the cruise control i occasionally get a surge, as if i just floored the accelerator. it doesnt happen all the time, occasionally it works fine. i've had my mechanic reset the computer several times but it has not fixed the problem. my mechanic also gets no error code. it shows up as everything is fine. he has the computer specific for bmw's so i know the comp reading, of nothing wrong is accurate. anyone else ever expierence this or hear of this and any solutions? thanks, rob marsh

Rob;
I have the same model 528i and I have had the same problem. The e39 528i came out in 1996 in Australia.
What I did to fix it was to removed the cruise control actuator, dismantled it and cleaned the feedback Potentiometer with alcohol and a pencil eraser.
Re-assembled, re-installed and it work like a charm.

Rob;
If you send me your email address I will forward on to you a copy of a pdf file which details how to disassemble the cruise control actuator. I have to send it by email as it is around 2megs.
I can't locate the Http: location that i downloaded it from.
If it's o.k. by the moderators
Cheers

Hey, Rob,
I heard about this lady, Mary Hill, whose Bimmer took off on her when she engaged the cruise control. 3 kids were in the back seat when she slammed into a tree. They all died and she's in prison forever. One was her daughter. So I'd get that cruise control fixed before you end up with acell next to hers.

I know this is an old post, but i feel i have to correct this. Your information about the crash being because of the "cruise control" is wrong. Thats what she said to police during the investigation. She went to prison for vehicular homicide because the investigation decided that she was at fault for the accident and was negilent in her driving. Eye witness statements provided to police said she was driving in an aggressive manner and speeding prior to the crash, and the one boy in the vehicle at the time of the crash had stated that he usually felt unsafe in her vehicle.
